A huge opportunity for material, time and manpower savings exists in the reduction of substation copper control cables. Read about American Electric Power’s journey to removing control cabling and replacing it with fiber-optic communication.

This paper presents a new Distributed Bus Protection System that is not only as a protection system, but also a platform that incorporates the data from the HV equipment in an IEC 61850 process bus scheme.

This paper outlines the high-level design principles for protection and control systems, illustrated using a practical solution for implementing ultra-critical protection and control IEC 61850 process bus applications.

This paper highlights trends and expectations of the electric power industry for the next generation protection, control and automation systems. Copper-based signaling and a simple, robust architecture are key elements.

This paper reviews cyber-security requirements for a process bus-based protection and control system, using NERC CIP as a reference. General attributes and functional requirements for a process bus network are described.

This paper discusses hybrid substation automation solutions, concentrating on the inclusion of alternate technologies. Evolutionary scenarios are used to highlight the conversion from alternate technologies to IEC 61850.
